Audio- / Video-Only
In addition to regular streaming, with the nanoStream Webcaster you can stream Audio-Only and Video-Only.
Audio-Only or Video-Only streaming is enabled by setting video or audio device to false
in the configuration object passed to startPreview(config).
Audio-Only Streaming
audio-only streaming
To start Audio-Only streaming, we pass false
to the video device configuration.
var videoDeviceConfig = {
device: false // setting a video device to "false" allows to stream Audio-Only
};
var audioDeviceConfig = {
device: 0 // we select the first available audio device
};
var config = {
videoDeviceConfig: videoDeviceConfig,
audioDeviceConfig: audioDeviceConfig,
elementId: videoElement
};
user.startPreview(config);
Video-Only Streaming
video-only streaming
To start Video-Only streaming, we pass false
to the audio device configuration
var videoDeviceConfig = {
device: 0 // we select the first available video device
};
var audioDeviceConfig = {
device: false // setting an audio device to "false" allows to stream Video-Only
};
var config = {
videoDeviceConfig: videoDeviceConfig,
audioDeviceConfig: audioDeviceConfig,
elementId: videoElement
};
user.startPreview(config);
